MN BH,
I would think that many of the farmers who have their land posted for the gun season would welcome you to take another deer afterthe gun season is over. Remember, though, the ND gun season is long starting this Friday at noon and ending 16 1/2 days later. Opening weekend is when the majority of the hunters are afield, at least the landowner/hunters who know where the deer are holding.
When it gets cold many of the deer bed in the same cattail sloughs that were hunted for waterfowl earlier in the season and many of these are waterfowl production areas open to public hunting.
As far as the stalking. I'd drive and glass likely looking areas in the morning and evening. I guess with a bow you may have to actualy see the area where the animal bedded down. We've also been successful in huntiing around waterholes with a lot of deer sign. This year that may work very well as much of ND is extremely dry.
PM me if you'd like.
Good Luck
